HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 757,445, dated April19, 1904.

Application filed March 31, 1903.

'10 all whom it may concern:

Be it known that We, J ACOB FIsHnR and AL- BERT CoRRoDI, citizens of theUnited States, residing at Columbus, in the county of Franklin and Stateof Ohio, have invented a certain new and useful Improvement inHorseshoes, of which the following is a specification.

This invention relates to horseshoes, and has for its object to providethe same with removable calks and in particular for applying theremovable calks to the heel portions of the shoe in cooperative relationwith the common or ordinary integral calks in such a manner as to beeffectually braced thereby.

It is furthermore designed to provide for reversing each calk when oneend thereof has become worn or broken and also to accomplish thisreversing of the calks without removing the shoe.

Another object of the invention is to provide for attaching the calks toany ordinary shoe without altering or changing the same in any mannerwhatsoever beyond forming an opening therethrough for the reception of afastening to secure the calk thereto and also to have the fasteningarranged so as to obviate loosening and displacement thereof.

With these and other objects in view the present invention consists inthe combination and arrangement of parts as will be hereinafter morefully described, shown in the ac-- com panying drawings, andparticularly pointed out in the appended claim, it being under stoodthat changes in th'e form, proportion, size, and minor details may bemade within the scope of the claim without departing from the spirit orsacrificing any of the advantages of the invention.

In the drawings, Figure 1 is an inverted perspective view of an ordinaryhorseshoe having the present form of removable heelcalks fitted thereto.Fig. 2 is a detail longitudinal sectional view taken through the heelportion of one side bar of the shoe in its normal position, and Fig. 3is a sectional view on the line 3 3 of Fig. 1

Like characters of reference designate corresponding parts in all of thefigures ofthe drawings.

For the purpose of adequately illustrating .Serial No. 150,407. (Nomodel.)

the application of the present form of calk there has been shown in theaccompanying drawings a horseshoe 1 of common or ordinary form and in aninverted position. This shoe is provided with any ordinary or preferedform of toe-calk 2, while the heel portions of its side bars are bent orformed into the usual integral heel-calks 3.

In carrying out the present invention there is provided a calk-body 4,one for each heel portion of the shoe and substantially rectangular inform,the middle of the body being comparatively thick and its oppositeend portions tapered to form sharp blade-like terminals 5 and 6. Throughthe thick middle portion of the calk an opening 7 is formed, and throughthis opening is inserted the stem portion 8 of a T-shaped fastening, thehead 9 of which fits in the angle between the sides of the calk, bearsagainst the latter, and is bowed or rounded, so that its end portionsmay snugly embrace the opposite side edges of the calk.

To fit the present form of calk to a shoe, the stem of the fastening 8is passed through the opening 7 of the calk and then through an opening10, which is formed through the shoe in a diagonal direction at thejuncture of the integral calk 3 and the adjacent side bar of the shoe.The outer or upper end of the stem 8 is of a length to project throughthe opening 10 and has its projected end portion screw-threaded forengagement by a nut 11, which is adapted to be set against the heel ofthe :shoe, and thereby draw the calk snugly into the angular seat formedby the integral hgel-calk 3 and the adjacent side bar of the s oe.

It will here be noted that the lower or pendent member of the calk 4projects below the integral calk 3 and. is inclined forwardly, so as totake into ice and slippery roadways when the foot of an animal isplanted upon the ground.

When the lower end portion of the calk has become worn or broken, thefastening 8 may be withdrawn and the calk reversed, so as to bring theend portion 6 into position for use. When not required, it will ofcourse be understood that the calks may be removed, as the latter areintended for use only when the slippery condition of roadways make themnecessary.

In addition to being removable and reversible each calk is efiectuallybraced by the adjacent integral calk 3, whereby there is little or nostrain upon the fastening 8, and hence breaking and loosening of thelatter are practically precluded. Furthermore, as the head 9 of thefastening is located upon the under side of the shoe and the nut 11 atthe top of the shoe and in rear of the animals hoof said nut is notsubjected to blows, and thus loosening of the fastenings is furthermoreguarded against.

Having thus described the invention, what is claimed, and desired to besecured by Letters Patent, is-

The combination with a horseshoe having an integral heel-calk, of anangular doublepointed removable and reversible calk fitted in the anglebetween the shoe and the integral calk, a headed fasteningintermediately piercing the removable calk and also passing through theshoe at the juncture thereof with the integral calk, the head of thefastening being at the lower end thereof and lying against the front ofthe removable calk, the upper end of the fastening being projectedexternally of the shoe and screw-threaded, and aremovable nut fitted tothe screw-threaded end of the fastening.
